Solar is becoming more popular
around the world to create energy efficiencies in novel ways. For example, India
is aiming to scale back their diesel consumption through the installation of
solar panels on trains that make up their massive railway system. While the
trains will still be pulled by a diesel-powered locomotive, the solar panels
will help power the lights, fans, and information display systems inside the
passenger coaches. It’s expected these simple changes will save the railway
about 21,000 liters of diesel every year.

Jim Tinjum rides his bike. He
rides it a lot. And right now he’s doing it for a good cause. As a teacher of
energy engineering and sustainability, he hopes to bring visibility and raise
awareness about wind energy via a 1,250 mile bike ride through the upper
Midwest that he’s calling#BiketheWind.

A satellite originally designed
to measure methane on Mars is soon going to be used to monitor methane
pollution across another planet—our own planet Earth. It’s set to lift off in
late September/early October, and will orbit the Earth up to seven years.
